VAT number validation, EU VIES

$0.01 per call · failed calls are never charged · no account or subscription: pay per call with a card key or USDC

Check an EU VAT number against the European Commission's VIES service: valid or not, and the registered company name and address where the member state shares them, with the check time. Accepts the number with its country prefix in any spacing (SE556703748501, DE 123 456 789, GR or EL for Greece, XI for Northern Ireland). Use to verify a B2B customer before invoicing without VAT, or to confirm a supplier.

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://agent-data-tools.revmesh2074.workers.dev/vat/validate?vat=SE556703748501"

Or one of your 25 free calls, no key:

curl "https://agent-data-tools.revmesh2074.workers.dev/vat/validate?vat=SE556703748501&trial=1"

Without a key, the same URL answers 402 Payment Required with x402 and MPP terms, so an agent with a wallet pays per call in USDC (Base, Polygon, Arbitrum or Solana over x402; Base or Tempo over MPP) and retries.
